A charging hood 22 that covers the inlet side opening 21a of the furnace main body 21 and is provided with an auxiliary fuel injection nozzle 23 in the lower part, and a waste charging hopper that is provided through the charging hood 22. 24 and the outlet side opening 21b of the furnace main body 21, and the combustion gas discharge port 25a is formed in the upper part and the incineration residue discharge port 25b is formed in the lower part. A hood 25, a combustion air supply header 26, which is provided annularly at the front and rear positions of the furnace body 21 and along the outer peripheral surface, and a combustion air adjusting damper 28, which are provided in the middle of the hood 25, respectively. Header 26 and furnace An air blow pipe 27 for communicating the body 21, attached to a peripheral portion of the furnace body 21, and the combustion air through the air pipe 29 is composed of a blower 30 for supplying the respective supply header 26.

In the above structure, the waste is supplied from the charging hopper 24 into the furnace main body 21 and combusted by the combustion air supplied from each supply header 26. That is, in the furnace body 21, for example, a drying zone, a pyrolysis zone, a combustion zone, a post-combustion zone, etc. are sequentially formed from the inlet side to the outlet side to perform predetermined combustion, and in each zone. The combustion control is performed by manually adjusting the opening degree of an adjustment damper 28 provided in the middle of each air blowing pipe 27.

[0004]

[Problems to be solved by the device]

 According to the above-mentioned conventional configuration, in order to control the combustion in the furnace body 21, the opening of the adjustment damper 28 is manually adjusted, so that the combustion can be controlled quickly and remotely. There was a problem that it could not be performed in the central control room.

Therefore, an object of the present invention is to provide a rotary combustion furnace for combustion that can solve the above problems.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the combustion rotary furnace of the present invention is provided with a combustion air supply header on the outer periphery of a cylindrical furnace body that is rotatably supported, and blows air into the supply header and the furnace body. A damper for adjusting the amount of combustion air blown is rotatably provided in the middle of the air blowing pipe through a turning device, and the turning device is driven through a power feeding device. It is configured to supply power.

[0007]

[Action]

 According to the above configuration, the adjusting damper provided on the air blowing pipe is rotated by the rotating device, and power is supplied to the rotating device via the power feeding device, so the adjusting damper is remotely operated. Can be activated by.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. Since the gist of the present invention lies in the combustion air supply part, only that part will be described in the present embodiment.

That is, in FIG. 1, reference numeral 1 denotes a cylindrical furnace body rotatably supported about a substantially horizontal axis, and a combustion air supply header 2 is provided in an annular shape at a predetermined position on the outer peripheral portion thereof. ing.

The supply header 2 and the inside of the furnace body 1 are communicated with each other through an air blowing pipe 3 for blowing air, and the amount of combustion air is adjusted in the middle of the air blowing pipe 3. An adjusting damper 4 for rotating is provided rotatably, and a rotating device 5 for rotating the adjusting damper 4 is provided on the furnace body 1 (or supply header 2) side.

An electric actuator is used as the rotating device 5. Specifically, the support shaft body 4a of the adjusting damper 4 is wound around a pair of gears 6 and 7 and both gears 6 and 7. It is constituted by an electric motor 9 which is rotated at a predetermined angle via an endless chain 8.

Further, the electric motor 9 of the rotating device 5 is provided with a power supply device 10 for supplying drive power from a power supply device (not shown) provided on the fixed side, that is, outside the furnace body 1. Has been.

The power supply device 10 includes a power collection line 11 arranged in an annular shape along the outer periphery of the furnace body 1, a power supply line 12 provided outside the furnace body 1 and in sliding contact with the power collection line 11, and the power collection line. The power supply line 12 is composed of a cable 13 connecting the line 11 and the electric motor 9, and the power supplied to the power supply line 12 is controlled by remote control from a centralized control room.

As described above, since the adjusting damper 4 provided on the air blowing pipe 3 is rotated by the rotating device 5 and power is supplied to the rotating device 5 via the power feeding device 10. The adjusting damper 4 can be operated by remote control, so that the combustion control can be quickly and centrally controlled.

In the above embodiment, the gears 6, 7 and the chain 8 are used to transmit the driving force of the electric motor 9, but of course, the present invention is not limited to this, and for example, the pulley and A belt or the like may be used.
